Abstract

Researching aspects of parallel architecture and system design concerning network processors requires excellent simulation tools. In this paper, we develop a tool called NPNS on top of a widely used network simulator ns-2, which combines full-system simulators to provide a unified framework for processor and software design within a network context. In this article, we describe the architecture of NPNS and its implementation issues. In addition, an example of simulating a multithreaded Intel IXP1200 network processor with NPNS is illustrated.
